Abstract

<P>PROBLEM TO BE SOLVED: To provide a guide light enabling space saving by integrating functions of an illuminating light to light a runway at night and a signal lamp notifying the state of the runway to a pilot from the ground and making light emitting positions of a blue-green color and a red color of an LED signal light in the same space. <P>SOLUTION: A plurality of blue-green color LED and the same number of red color LED are installed on an LED base in circles in parallel to each other. The lights have water proof functions by being sealed by lens and bodies, operated by a power source (an integrated battery to maintain the lit state of the blue-green color and the red color in a power failure during the guiding of an air craft or a space craft), the red color is lit when the landing strip cannot be used and the blue color is lit when landing is possible by a switch operation cable. Then, the lights are installed on both sides of the runway or the landing strip of an air port or a space port. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

Detailed Description of the Invention

  The technical field to which the present invention belongs is the field of illuminating lights that illuminate the runway at night, the field of signal lights that visually inform the pilots of aircrafts and spacecrafts about the landing possible state of the landing road, and the LED (light emitting diode) signal lights Is a field.

  The runway at the current airport includes an illumination light for illuminating the runway at night, a signal light (signal system) to notify the pilot of the runway status from the ground, a laser notification system, and the runway status to monitor There are monitor systems that display an enlarged image. In addition, when the lights are turned on and off at night, only two parallel runways can be installed at the airport.

Problems to be solved by the invention

  The problem to be solved by the present invention is to integrate the function of an illumination lamp for illuminating the runway at night and a signal lamp function for notifying the pilot of the state of the runway from the ground. And space saving is realized by emitting the blue-green and red light emission positions of the LED signal lamps in the same space. Light bulbs and LED illuminators have different runway images at night and daytime, so the recognition of the landing process depends on the landing time. Because it uses a light bulb, it uses a lot of power. The product life of the bulb is shorter than that of the LED. Also, the extinguishing time until the power is supplied by the emergency power generator is not lit. The light bulb emits light over a wide range, and only the central part reaches far.

Means for solving the problem

  A plurality of blue-green LEDs (1) and the same number of red LEDs (2) are arranged in a circular parallel arrangement (3) on the LED substrate. Sealed with lens (4) and body (5) for complete waterproofing, power supply (6) (blue-green / red lighting during power outages, etc., until the start of power transmission by emergency power generators during aircraft / spacecraft guidance) During operation, the battery is operated with a built-in battery (7) for maintaining the lighting state, and the switch operation cable (8) lights red when the landing path is not usable and lights blue when landing is possible ( 9) Let it go. And it arrange | positions (10) on both sides of each line of the runway and landing road of an airport or a space port.

  Power switch cable wiring is embedded in concrete at 25 meter intervals on both sides of the Haneda airport runway, resin lens, 0.5 mm thick aluminum plate body outer diameter 250φ, LED base outer diameter within 250φ, built-in battery, power supply 800 operating single-light and two-color light-emitting guide lights are arranged. When a runway resident monitor is deployed and there is an airplane on the landing road, it lights up in red to light up the red state of the landing road. Light up in blue is confirmed by the control center monitor monitor (monitoring camera) or runway resident monitor.

If a plane is on the landing road when a monitoring camera is installed and the control center monitors, the red state of the landing road is emitted using a system that automatically lights up in red. Light up in blue is confirmed by the control center monitor monitor (monitoring camera) or runway resident monitor.

When the airplane is on the landing road as detected by the infrared sensor, the system automatically lights up in red to light up the red state of the landing road. Light up in blue is confirmed by the control center monitor (monitoring camera) or runway resident monitor.

The invention's effect

  Piloting from the ground the lighting and runway conditions to illuminate the runway at night by arranging multiple blue-green LEDs (1) and the same number of red LEDs (2) in a circular parallel arrangement on the LED base (3) It is possible to integrate the function of a signal lamp for notifying to. Further, space saving can be realized by causing the blue-green and red light emission positions of the LED signal lamps to emit light in the same space. By always emitting light at the time of landing, the images of the runway in the daytime and at night can be matched. An LED that emits light by a pulse width modulation (PWM) method with less heat diffusion uses less power than a light bulb and has a longer product life. By incorporating and integrating the battery, the waterproof effect is enhanced, and the lighting state can be maintained during the extinguishing time until the power is supplied by the emergency power generator. Since light is emitted from a plurality of LEDs, the light emission color is not changed by image compression or the like, and the light emission state can be confirmed from a distance. In addition, landing may be possible in the case where the landing has been stopped conventionally, so that the landing process becomes efficient.
